Small, efficient and uncompromisingly stable - the M ONE X is a highly compact monoblock for subwoofer applications. Designed from latest Class D technology this tiny amp can easily control speakers with 1 Ohm impedance. Its current capability makes the M ONE X a perfect partner for 2 x 2 Ohms subwoofers, where both voice coils are connected in parallel. And for even more output power, two M ONE X amplifiers can be combined to one single powerhouse – thanks to the TwinPower Link.

In addition a comprehensive and stunningly practical feature set leaves nothing to be desired. Last but not least installation will be a no-brainer due to the minimal dimensions.

  • Small footprint Class D amplifier with up to 1,180 Watts RMS output power @ 1 Ohm for easiest combination with all 2 x 2 Ohms subwoofers connected in parallel
  • Start-Stop capability down to 6V supply voltage
  • Smart highlevel input with ADEP circuit and Auto Turn-On function
  • Integrated, active crossover with lowpass, bass boost, subsonicand phase control
  • TwinPower Link for connecting two amplifiers in bridged mode
  • Bass remote control for volume adjustment
  • Low heat dissipation thanks to extraordinary efficiency

 

Special features:

Smart highlevel input
The latest generation of OE car radios incorporates sophisticated possibilities of diagnosing the connected speakers. If a common amplifier will be hooked up failure messages and loss of specific features (e.g. fader function) quite often appear - but not with the M ONE X.
The new ADEP circuit (Advanced Diagnostics Error Protection) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability
The switched power supply of the HELIX M ONE X assures operation even if the battery’s voltage drops down to 6 Volts during engine crank.

OLEVS Men’s Watches Waterproof Dress Minimalist
Color: BlueFace-G5010
I got this watch for my husband, and it fits him perfectly. He’s retired police officer but still carries himself sharp, and this watch matches that classic, put-together look. The blue face is rich and eye-catching without being flashy. The Roman numerals and silver detailing give it a timeless, elegant style. It looks much more expensive than it is. The black leather-style band is comfortable and fits well. It’s lightweight enough for everyday wear but still feels solid and well made. The day and date feature is clear and easy to read, which is a nice practical touch. Whether he’s dressed up or just heading out casually, this watch pulls everything together. It’s a great combination of classic style and everyday function, that’s easy to set up.

Nice basic watch
Color: Black Watch-G5010
My father-in-law does not like new technology so when I saw this wat I knew he'd love it. It is your basic watch, works well and it's waterproof so very helpful as he fishes a lot! The overall appearance of the watch is really elegant; the watch itself is thinner than most which gives it a really nice look and I was really surprised at how good the quality is on it. It comes with the little tool to tack links out so you can adjust the fit and I feel like it looks nicer than his more expensive watches. So far, it's kept time well and he's been extremely happy with it!

Clean simple design looks sharp, a nice watch at a great price
Color: Black Face-G5010, Color: Black Face-G5010
This watch has a nice big face that looks elegant in simplicity. The hour indicators are raised and very shiny along with the hands. On the black face, it’s very easy to read. The one that I have has a soft strap so you don’t have to remove any links. It’s ready to wear out of the box. I don’t know that the strap is leather, but it was stiff and in working with it a little bit to loosen it, it appears that it will hold up well. I wondered if it would be fragile, but it doesn’t seem so. The soft strap makes it comfortable and maybe a little lighter so it’s easy to wear this watch. Overall, it just seems like a very well done watch and a great value and a very least a very fair value.

Better options for the price
Color: Black Watch-G5010, Color: Black Watch-G5010
While having a striking appearance, the band has many rough edges and pulls your arm hairs. It is a good size and looks good at the surface level, but it is very light almost to the point that it feels cheap or not durable. This makes the price feel unnecessary, especially when compared to other more substantial or quality feeling options at this price point and below. If you just need a watch, it’ll do but I felt that it fell short in places, especially the band.
